Correction. 

The  valuation  of  H.  J.  Baker  &  Bro's.  A.  A.  Ammoniated  Super- 
phosphate, sample  No.  752,  published  in  Bulletin  No.  70,  June 
30,  1882,  and  in  Annual  Report  for  1882,  p.  30,  is  incorrect. 
By  a  misplaced  decimal  point,  the  estimated  value  of  insoluble 
phosphoric  acid  was  made  $7,44  instead  of  $0.74.  This  error  was 
not  detected  in  the  duplicate  calculation  which  is  always  per- 
formed, before  the  Station  valuations  are  put  on  final  record. 

The  erroneous  valuation  of  No.  752  was  $50.43. 

The  correct  valuation  of  No.  752  is  $43.53.
